Enum double_map::dhash_map::ErrorKind

pub enum ErrorKind {
    VacantK1AndOccupiedK2,
    OccupiedK1AndVacantK2,
    KeysPointsToDiffEntries,
}

A view into an error kind returned by entry, insert, try_insert methods of the DHashMap. It is part of the EntryError structure, InsertError structure and TryInsertError enum.

Explains why entry, insert, try_insert methods fail.

Variants

VacantK1AndOccupiedK2

Returns when key #1 is vacant, but key #2 already exists with some value.

OccupiedK1AndVacantK2

Returns when key #1 already exists with some value, but key #2 is vacant.

KeysPointsToDiffEntries

Returns when both key #1 and key #2 already exist with some values, but point to different entries (values).

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ErrorKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ErrorKind

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
